Abstract
The socio-economic objectives of transport projects are generally related to the improvement of travel conditions for goods and passengers as well as the improvement of the quality of the environment and the wellbeing of the served population. Railways infrastructure projects are always complex because of the many variables involved. In railway rehabilitation, in particular, social, economic and environmental variables take on considerable importance. These variables contribute strongly to the selection of the intervention project to be performed. Historically, multicriteria evaluation methods were developed to select the best alternative from a set of competing options. Multicriteria Analysis is applied for comparison of alternative projects, allowing taking into account different criteria simultaneously. It presents a framework in which all the stakeholders can participate actively in the process of decision making and in the explicit resolution of problems. The paper intends to frame the multicriteria analysis with the purpose of its implementation in railway investment projects concerning rehabilitation interventions. In this sense, its importance and potential will be highlighted for several stakeholders in the decision-making process, as well as the objectives and criteria definition for a practical implementation.
Highlights
Multicriteria analysis emerged in the 1960s as a decision support tool, and it was immediately applied in the elaboration of comparative analyses of alternative projects or of heterogeneous measures
Multicriteria analysis can be organized with a view to producing a simple synthetic conclusion at the end of the evaluation or, on the contrary, to produce conclusions tailored to the preferences and priorities of different stakeholders
The multicriteria analysis is like the techniques adopted in the field of organizational development or management of information systems and resembles Cost Benefit Analysis
Summary
Multicriteria analysis emerged in the 1960s as a decision support tool, and it was immediately applied in the elaboration of comparative analyses of alternative projects or of heterogeneous (multicriteria) measures. The multicriteria analysis was most recently used to gather the views of different partners and stakeholders in the evaluation of a regional development program co-financed by the three European Funds (the Structural Funds, the Cohesion Fund and the Instrument for Structural Policies for Pre-Accession). The multicriteria analysis fits well with the management and evaluation of structural programs in partnership, as the views of national and supranational members can be expressed together, without losing any of their specificities, or without making too much concessions on their scales of value [2]. The present paper intends to frame the multicriteria analysis with the objective of optimizing investment projects in the rehabilitation of railway infrastructures. In this sense, its importance and potential will be evidenced for various stakeholders in the decisionmaking process. Some preliminary remarks of the study under development will be presented
